"Scott was able to come out quickly and diagnose the issue I had with my old heat pump. He gave me options to repair or replace. Considering the age of my heat pump was far beyond its expected lifespan, I went ahead and asked him to replace it. He got the parts ordered right away and I had a new unit within a few days. The new system is working great and I was happy with Scott's professionalism, communication and cleanliness. Highly recommended."

"Shane was really great! He walked me through potential causes for the dishwasher to not work properly; parts needed to repair, and time and cost. He picked up the parts from a distributor and installed them. The total service time was around 2.5 hours. My wife and I are ecstatic the DW is fixed, because we did not want to buy a new one. I will definitely use HB again; and in fact, I have purchased a Home Protection Plan with them."

FAQs for air conditioning projects in Rockvale, TN

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
